buona serata, I hope you are well! tomorrow, there will be two presentations by our guest veronika baumann from iqoqi and tu vienna. the first one will be at 11:00 in the fifth floor's meeting room, and the second at 16:00 in the interior court if weather permits. hope to see you all tomorrow! stefan 11:00 Title: Different perspectives in (non)-causal quantum processes processes Abstract: The process matrix framework was developed to allow for scenarios with indefinite or quantum causal order, a phenomenon that is expected to be relevant for quantum gravity. A popular approach towards a quantum theory of gravity is the Page-Wootters formalism, which describes time-evolution of systems via correlations between a clock system and other quantum systems encoded in history states. We combined the process matrix framework with a generalization of the Page-Wootters formalism with multiple clocks. Each of these clocks can be thought of as corresponding to an agent and conditioning on a certain clock gives the respective agent’s perspective inside an a priori general quantum process. We implemented scenarios where different definite causal orders are coherently controlled and explain why certain non-causal processes might not be compatible with this framework. 16:00 Title: Psi, reality and interpretations of quantum theory Abstract: A random selection in agreement with the title :)
